Between Worlds (Lustful Desires Crossover)

The 0.10a update brought us a special crossover with lustful desires, another VN i GREATLY recommend developed by Hyao (if you are liking this game, i almost guarantee you’ll dig that one too!).
This crossover in particular “borrows” Roushk (a big sexy lizard, without giving you spoilers), while we “lent” them our own beloved lizard, Nauxus.

This event is triggered after these conditions are met: you need to have met Meko in "Hakan's quest to get buzzed (part 1)" (part 2 is not necessary anymore), and have attended at least one of the first lessons of the chiefs ("the first lesson") (so after "setting up camp - the war (part 2)") .
actually, The event will vary a bit according to how you have completed the camp quest, i’ll write about all 3 versions below.
Also, the very last part of the quest has a slightly different dialogue if you have played Lustful Desires, based on your actual route with the tribe in that game (you don’t need to link or patch anything, Tavern of Spear will know, we know if you are a bad boy...or worse).

Once the conditions stated above are all met, the event will begin automatically the next time you go to the map, and will be forced to get back to the tavern and go scout with the 2 loveb- i mean, the 2 scalies of the tavern ;p.
After this amusing scene, you are free to proceed whenever you want, by going to the swamp during the day (west of the lizard village), but note that, since that’s the place to continue, you won’t really be able to fight any rogue lizard until you proceed (in case you wanted to see a sex scene or get some lizard scales).
Once there, you’ll face a rogue lizard and then a big red lizard, Roushk (even if you’ll find out his name only in the scene after winning). Since Roushk is immune to teasing, and won’t tease you either, i suggest keeping your MP for him, maybe 2 or 3 HP potions at hand if the rogue hit a lot, he hits fairly hard, so i recommend using the holy fist immediately and use potions during cooldown to save MP, throw in a regular attack if you can, 3 holy fists and a couple of attacks should be enough to deplete his 250 HP.
Losing either battle will lead to a bad end (without a sex scene, nor death, it can still be hot and fun to see!).
After the battle, you’ll carry Roushk back to the barn, and you’ll eventually be given the choice to “fight back!” or “run and get help!”: the former will give you the top scene way later with Roushk, while the latter will result in you bottoming, effectively requiring you to play the event twice to get both scenes.

The following lines describe the event in its entirety, there are slight variations if you helped Nauxus or Axel during the camp quest (described in the notes below):
meet Roushk in the barn in the morning (6:00-11:55) to go meet Selye. The lizard trio you have already met during the camp mission properly introduce themselves; Nuo, Duo and the mighty Blep then fight you and are actually better than their silliness would lead you to believe, they do count as a single enemy, but all have their way of attacking, be it to hurt or arouse you, even with team attacks, they have 250 HP, but do moderate damage and lust damage and waste turns fairly often, going all out with attacks or even fists should get the job done, but they can be teased easily too (plus, the scene for winning by lust is funnier); by winning, you gain 1 level up point, but the punishment for losing is giving up 20% of your current money (so, if you somehow can’t seem to win, buy stuff and lose on purpose). (Fun fact: the trio is a reference to the barrier trio from Mother 3).
Note: if you helped Axel during the camp quest, it means you have killed the trio already, this means you won’t fight them here: a guard is gonna tell you Selye isn’t home instead.
Unfortunately, Selye (and Nauxus) aren’t home, so this was all for nothing; the next task is talking with Thane to get Roushk to the temple without other bulls seeing him. Also, if you go talk with someone from the tavern, you’ll get to enjoy some fun interactions between them and Roushk (only the first time you talk to each, and yes, even the passed out guy next to Hakan...kinda).
Just go speak with Thane (remember he is not around at night), then get back to Roushk, then, to proceed to the temple, speak with him again when it’s dark outside (18:00-5:55).
After a long scene, Tomahawk will spot you on the way back, and this leads to another fight; this strong bull warrior seems to favour tease attacks, also, despite his whopping 400 HP, Roushk will actually help you in battle, dealing good damage consistently, thus, high END and AGI builds are probably slightly favoured, so the battle drags out while Roushk does his job, INT helps too, to heal more or finish Tomahawk with 1 or 2 holy fists; winning or losing has pretty much the same outcome, but winning rewards you another level up point.
Note: if you helped Nauxus during the camp quest, it means you have killed Tomahawk already, a guard is gonna spot you regardless, but Thane will lead him away and spare you this fight.
For the last part of this route go talk to Meko, then to Roushk, and go meet him, he will be possessed by the bracelet’s spirit, a very humble guy, calling himself “the boss”; this really feels like a boss fight, lust attacks are useless, it’s a fight to death! (or, well, until that spirit is vanquished), so you can’t afford to lose this one (also, its max lust is a nice touch ;p); the boss has 400 HP, and a variety of attacks to hurt you, but Your strength, agility and defense are improved for this fight, it shouldn’t be too hard (definitely possible without potions).
Now it’s time to celebrate, Roushk can finally get home (unfortunately), the party is from 18:00 to 22:55 in the tavern, this is the only way to get the sex scene with Roushk (top him if you selected “fight back!” or bottom for him if you chose “run and get help!” after you fought him); from 23:00 to 5:55, Meko will chastise you but make sure you will be there to see him off, or, if you get back to the tavern after 6:00, he will already have left, and Snow will give you his bracelet in his stead.
The event is over, but everyone will have a last comment about Roushk the next time you talk with each, you also get 3 level up points, and his bracelet (100% guaranteed free of curses ;p which gives +1 END and +5% crits).
Nauxus is back now too, he is gonna comment the next time you enter his room, and his dialogue varies if you have played Lustful Desires, and depending on the route you took there for the lizards.
