How do you exit the lair? There's a corpse there and it has a USE icon, but nothing happens. Do I have all the loot from the Kayran? The journal says go collect your reward. Sile is just standing there inspecting a tentacle.

same way you went in, obviously.

Climb up, to the same ledge you were on when the cutscene started.

You collect your reward from the merchant in town.

There are two loot spots on the dead Kayran. So make sure you hit both spots. As for leaving you have to walk back to town. Just do the same thing you did to leave the area when you were there with Triss earlier in the game. Remember when you investigated the ship wreck? You left by climbimg back up the rocks so just do that again.

Okay, I'm standing next to Sile as she examines a tentacle. Everywhere I go is blocked by the body and tentacles. I have no clue where this ledge is to get out..

Trust us, it is there. I guess it'd be behind her (ish). Opposite side from where the river and boat are.

If the broken bridge is on the west side and the boat on the east with Sile and the dead Kayran in the middle, the ledge you're looking for is in the south-west corner - directly south from where you found the dead body.

Dunno if that's how it is on the map - but you should get it from this.

If it works for you, please mark as solved. Thx

Well, I know exactly what this is like ...

I'm one of those players that is good in combat, but has the worst sense of direction ever.
The Kayran lair, I had to hug an edge and go along it until I found the ledge ... and when I did that I found that I went the wrong way and did a circuit around 90% of the place.
