Fly.

Concentrating on the gem it doesn't talk to you exactly, but all the same you know that you have quite some distance to travel. Not only in distance, but you first hurdle will be getting out of this dimension, or plane, or whatever the hell you should call it. The gem seems to give you two paths to follow at the same time, one is very faint and appears to be the direction you need to go, but not the shortest path. The second leads off in another direction entirely, but must be a shorter distance somehow as the course seems much stronger. Flying up into the air to get a good look is exhilarating, the air seems to part with every mighty flap of your wings. However you instantly realize how stupid of an idea it was to simply fly, considering you are a creature that is an enemy of every creature in this plane. Looking around you see what looks like 100 or so little bat winged creatures with wicked looking claws, fangs, and horns. “Awe fuck.” Is all you can say as you head in the only direction that the sky isn't full of demons. Sadly you have no real rout as the second you make any headway getting away from the mass of demons, you spot another. You seem to be the talk of the town, a Erinys in the depths of whatever place this is. “Fuck me I should have listened. They are going to rip me apart.” Then you spot an even bigger problem, something massive. What seems to be a small troupe of 30 creatures, all easily 12' tall with massive bat wings, horns, cloven hooves, and claws as big as your arm. “Bad really bad.” Then you finally remember your powers. You bring up the mental image of where you first arrived here. In an instant you are surrounded by high rocks, with no sign of what was chasing you. “Ok, so how the hell do I get out of here?” Kicking a rock with your pretty little toes, you decide to try something. Staring at your sexy feet you visualize cloven hooves and the extra joint like the massive creatures, as you do the bones in your legs crack and break, your toes merge together, and in a few seconds you now have cloven hooves. “Eeh, weird.” Clomping around in a circle for a few minutes you further morph your legs till you can actually walk pretty well. “Ok now I need horns, claws, darker skin, and bat wings right. But I can't see... Hmmm” But you realize you don't really need to see, as it is all mental anyway. You bring the image to mind of sort of a cross between the massive creatures and the small ones, A pair of big bull like horns sprout from your head, as they do you also sprout a mane of coarse black hair that covers your head. Your form hunches a bit and your wings solidify and become like those of a bat with large hook like claws at the joints. Fangs grow in your mouth and claws form on your fingers, and your eyes burn as you do your best to get them to glow deep and red. Lastly your skin darkens to the hue of a bad bruise.

With a new found disguise, you once again take to the air. Flying on the new wings seems more powerful while far less graceful, and far less controlled. The feeling is still quite amazing, and this time the little critters all over the place now seem to see you as a potential threat or superior as they seem to slightly alter their path to get out of your way rather than deal with you. The only thing to do now is to decide whether to go what seems to be the direct route or take what must be some kind of short cut, one that feels like it must be a more direct portal of some kind. Probably guarded too.
