It can be explained for acrobat, and I don't think heroes could get fly before Zyla came along. Thankfully, heroes cannot have soar...yet.
Wings of Regiroth are a gold treasure from WoD which grant fly. It's rare, but if could happen. I actually missed the part about heroes not getting soar in our last campaign and used a Crushing Blow on those wings so that Kratz the plague couldn't be hit by a melee attacker. Also, along with Zyla comes the "Carried by Air" feat which gives a hero +2 speed and fly for a turn.
