Is Elrond a unicorn?

Could you please clarify for me whether Elrond, as mentioned in the context, is indeed categorized as a unicorn? I'm rather perplexed as to how he could possibly fit into such a description, given that I'm familiar with the concept of unicorns as mythical creatures with a single horn protruding from their foreheads, whereas Elrond, to my knowledge, belongs to a very different realm of existence and legend. Is there some deeper symbolism or interpretation at play here that I'm not grasping? Or am I simply misunderstanding the question altogether? Your clarification would be greatly appreciated.
