Orven, the Sigil Stealer/Breather

All I have time to think of (before work in 10 minutes) is Orven having this ability (he's a toplaner) where his throws down this massive sigil/crystal in the dirt and he tries to defend it for like, 10 - 20 seconds. I have a few ideas: he either has to prevent ANY damage to it for a period of time, or the sigil has 500hp or so and if he defends it for the growth period, a large radius (about half the size of toplane) he becomes super buffed and ready to fight for 30seconds? Otherwise he's pretty weak maybe? I'm thinking of as the base archetype with his pillar and his W frozen area radius thing.

I'm not sure if it'd be cool for Orven to be able to place multiple ones on the map, and have them be permanent until killed. Also, I feel thematically and balance-wise that Orven wouldn't be able to place them on his side of the map, or too close at least.

Maybe thematically his backstory he's trying to rule/control the world kinda like in "GUARDIANS OF THE GALANXT VOLUME 2" where the bad guy was planting those glowing things on every plant in order to become ONE with all things and become unstoppable. I think that'd be really cool.

Also archetype wise, as you can see from my picture, I kinda think of . Those two kinda inspired me for this champ.

He'd be melee range (of course) and I picture him as a tank even though I don't want another tank. Oh well.

I feel like instead of having cc, he'd just super buff himself instead. I feel like should counter him fairly easily. Also should counter him easily since she can poke his sigil down really easily with her Q. He'd be an engager, but would only be successful if he could have a sigil or two in the dirt beforehand. He'd be like Azir where he's good at objective control (baron + drake).

What you think?

Enemy champion interactions would make fun of him looking like a rooster. "Funny, chicken-man."

And yes, I'm 20 years old and my drawing looks like a 12 year old lol. Cy@
