Yeah, there's a snowy owl thing companion called a Lapistrix. They're hard to get but you can see one in the second sword thing on the Icerun Campaign.
Ah yes, a fellow bird and D&D lover! Hello and welcome c:
There's an owl companion you can get for moonstones (premium currency, but you can slowly earn it by playing, too) in the Mole Market sometimes. The inventory is random and refreshes every six hours, you'll find it there eventually. You can see it on this wolf here!
And there are the Snowloons. They're owl-adjacent, if that counts? Also in the Mole Market, but for regular pebbles (I think 350,000? someone correct me if I'm wrong haha). I haven't gotten them myself yet, but there are two variants, one grey, one blue-ish.
Hope you've been enjoying your time here so far! There's a lot to do and it can get confusing, so if you ever need help - feel free to reach out and message or ping me. ^^
I also give away free wolves, if you'd like to add a few to your den! - Click!
