R Idea 1 - Reinforcement - Khaad channels for 2 seconds, after which a portal at his fountain will appear for 1 seconds. Allies can right click on the portal to channel for 4 seconds, where they will then be teleported to Khaad's position. Damage interrupts both Khaad's, and his allies channel. Enemies can see both Khaad and and his allies while they are channeling.

R Idea 2 - Reinforcement - Khaad channels for 2 seconds, after which an ally can right click on Khaad or his portrait. When that ally respawns, they will respawn at Khaad's location. Damage to Khaad interrupts the channel, and refunds 75% of the CD.

Appearance Khaad looks similar to a giant golem, with towers and keeps sculpted from his body. Similar to this. Credit to Magna-Omega for the image

So that's about it, I don't have any lore done for him, but maybe soon.
