Arachyr, according to the Tomes of Creation, was the first creature created on Sanctuary, and as such, is the 'father' of every creature of the world that followed. He is often represented as a spider, but there is much debate as to how many legs he actually had. Much like his offspring, it is said he can be charmed to do ones bidding-but often turns on his supplicants with no warning. However, Arachyr is not malicious by nature: his actions are thoroughly purposeful, and their main purpose is to amuse himself.
The strength of Arachyr's children lies in their unpredictability.
- Arachyr's name is possibly derived from Arach root (Greek "Spider"), which, in turn, comes from the myth of Arachne, who was turned into a spider by the goddess Athene.
