Weaslans are entities that are mostly passive for the most part. If you hear any noises or footsteps at night, it's probably one of them. The reason they are considered passive is because they just stare at people and observe them. Although, there are another type of Weaslan that walks on all fours. These are called "Evolved Weaslans". These Weaslans DO kill. Weaslans do not speak any languages.
the rake !?? also no you cannot fight a Weaslan with only your fists, they have really strong hands. You'd need a gun or something to kill a unevolved Weaslan. If they are evolved, you might as well get something that'll burn them or drown them with (They can't swim)
