What level are you atm? Pteras are weird in that they sit low on the kibble chain but a saddle for riding them is lvl 35 or 40. If you haven't leveled all that much I just rerolled on a pve official server with the new map. Joined a newly formed tribe (3 of us, all admins) and can offer you (or other bit techers) a spot if you fancy it. I'm only 26 on this server but it's coming along nicely.
