I very sincerely doubt Élev could help us in any way
He could eat the corpse?
Nooooo! He could do MUCH MORE than eating the corpse!!!
OK, maybe not that much... Arrgh! But let me explain!
Élev doesn't need to be near to help us! OK, it would be preferable, but... anyways! He would probably have just enough time to teach us how to turn invisible and hide our spiritual traces, and that is exactly the advantage we need against a bunch of crazy death sorcerers AND a mob of ferocious maws!
Also, it appears unfeasible to me to teach fire magic to Flax in a very short timespan, so if someone truly has the capacity to burn a giant carcass fast enough, it is clearly us. But to reduce the time of our travel, we totally can use the same wind magic that allowed us to increase the speed of Uzin's hunting party!
Moreover, it is clear to me that Élev will want to help us, because he is a shaman just like us, and it is his duty to protect the natural world. And he told us that his race was hunted by men for a long time, and being a very knowledgeable shaman, I'm sure he knows about that Melabil organization, "the grand iron girdle of the north". Especially that its members are probably persecuting the animal people, since in the dream, there were chained otherworldly beasts, and I'm pretty sure many of them were sentient as it would be very strange to have plenty of wild beasts around dining tables in a grand hall.
But even if it wasn't the case, animal people are definitely at risk of becoming endangered if an undead titan starts roaming into every corner of Wintervale! Then let's remember that there was a wolfman in the hall, wich is a very peculiar sight around humans, so maybe he was paid into tribute to them when he was a child, wich a custom of wolfmen like we have explained to Flax in another story part, and that would point toward the subjugation of wolfmen clans by the same humans.
Besides, since Élev is seemingly a seasoned shaman, he must have some influence over wolfmen, and if ever we don't manage to overcome our enemies, wich is totally possible in view of their numbers comparatively to ours, he might have the time to make an ambush of wolfmen on the depleted forces of the bad guys when they will be returning to their base in the west bank barrows with their heavy loads!
Afterward, as pertains to the presence of a new voice in our spiritual mind, I see it as a very positive thing, because Élev might give us some advice to cope whith our inner wraith, and when that same darkened being will start to win over our conscience, there will be a friendly wolf voice into us to help bring us back on the right track. But in fact, while it is evident that Crackantler is already tainting us, I'm afraid that it will become considerably worse if we have to kill plenty of people and if we get surrounded by the dark auras of several death sorcerers.
And by the way, the very actuality of the blackening of our spirit couldn't have been more wonderfully illustrated than by the absence of pain when we cut ourselves in the beginning of the dream, and by the serpents creeping in our antlers, wich probably represent the roots of evil pervading our mind, slowly transforming us in a stone hearted deer, just like the stare of the Gorgon would have done in a flash.
So in conclusion, I think we really need to bloodbind us to Élev!
Sorry Quaksna if ever my post dismantle everything you are preparing!
