Art I tried to make a concept art (it didn't work but here you go)

I am not an artist and did this for fun. Maybe someone will like the concept and make something better. Feel free to!

"The Altar of Convergence: Located in the center of the realm of war, this altar is directly below the spot where light and dark have clashed since the beginning. The scarlet energy emitted at this point is the densest source of corruption in all the realms and is the origin of all corruption in this realm. Recently, the Dern Beast has utilized an altar to convert the corrupt energy into pure darkness, turning the tide the War of the Realms by absorbing all this additional power. Surrounded by a fortress, destroying the conversion altar would, in theory, bring the darkness's power back to normal levels and limit its ability to influence those in Gavel. It is easier said than done, however. Bak'al, once a creation by the Fruman queen to destroy the altar, then corrupted by the realm, has been tasked with guarding it at all costs. Additionally, you sense... something, no, someone familiar to you nearby. Once an ally, now tainted by darkness and merely a tool of the darkness, Lari's decayed form can be seen with Bak'al at the top of the castle wall. Prepare for Battle."
