Here are old (some older that others) sketches of Masked Spirits. Boring!

They all have names.
The one on the top left is Ettore. He's super old. The one next to Ettore is Yulanzuk. He's quite old too, and yes, that is a fish fin. The one on the bottom left is Ecek and below him is Oruan. I have no idea what Ecek is, but Oruan is an owl. We see Zanebono, of course, who is freaking the hell out because his fur is changing color (Zanebono's fur turns white for the winter like an arctic fox). The creeper in the middle is old, and I recall him being named 32. He's a huge nightmare/acid trip. I remember him being involved in some nightmarish paintings once upon a day. He likes to eat souls.

Thanks for looking!
