6.17.3 Trees

Every location in Aetolia of Forest, Jungle, or Garden environment type has
trees that can be climbed up in, if you have an ability to let you do it in
your guild skills, or the relevant ability in Survival.

While in the trees, you can move around with the same exits as the ground has,
but if you move into a location with no trees, you will fall out and perhaps
break a limb.

Oftentimes, you will find that those who lurk in the trees above you are
spying on you or preparing to do you harm, so be careful and discover ways to
see if anyone is in the trees above you.
