Hes made of gems and all, does Tarics family worship Skarners race?

No. Taric comes from a different world.
I'm sure he does find Skarner extremely interesting though.

Maybe he wants to decapitate and flay Scarner for the most magnificent armor ever worn by the King of Bot Lane?

Oh hey, idea, a purple Taric skin with some added lore: Crystal Scorpion Taric

huh, never realized taric was from a different world,

id still like to consider skarner as a steed, for whats a knight without a steed

kapaw

I'll be more worried about what Taric would do when he goes on a safari hunt....

I mean... Crystals are one thing, but organic crystals that grow off a being? He must be dying to try out the magic that lies behind those crystals.
