One of the strangest customs of the Na'vis was that when they reached the age of fifteen they could mate with whoever they wanted without performing the Tsaheylu. Normally this custom was carried out on full moons, when the na'vis of fifteen or older entered into heat.

Today was a full moon, and from early on Neteyam could already feel how his body was heating up due to heat.

Finally at night Neteyam was looking for the only person he wanted to spend his heat, you. He found you in the forest and approached you kissing you and pulling you closer.
