Also, since you are adding animals theme, maybe let every realm to have an animal as a symbol, but just one. This way it would be more orderly, I think. And we can think on less common animals-symbols (lions and wolves are used kinda everywhere). For Ikalak something representing chivalry - maybe an eagle, or a war horse? For Tasalak something representing strength and power (I personally would prefer something dark) - wolf, or, maybe, black panther? For Sandalak it might be something related with wisdom - a big snake (like python) or raven.
