In simple terms. Void is Ice, because Fire, Lightning, and Ice make up the 3 elements of Magic. We use "Space Magic".
In complex terms. Void is "Space". Space is the complete absence of everything, which includes heat. Which leaves only cold, which is the absence of heat. Cold is nothingness. The Void is completely cold. Therefore Void fills the "Ice Element".

No, I got what you were saying. That's a logical way to fit Void into the typical fantasy 3-element gig. I just don't really see Void that way. I don't think they worked through that same thought process, I think they just picked something else.
