Kratenex

Kratenex (also known as Nex) is a hallucinogenic drug made from crushed Krats, taken intravenously with a needle. It creates vivid, colorful visions. The player can share a fix with Nkaanmykiunsuns during her cuddling scene.

During Nkaan's trip, the game checks for a flag "pc_hidden_hand" (where pc stands for player character) and one screen of text differs based on it. It's unknown what this means as there is no other mention of this flag anywhere in the game.
