OOC: Tsathzar Rho was one of the most feared mages of his time, and specialized in demonic summoning. He arrogantly thought he could summon and control the Elder Gods of the Outer Realms, thinking they were simply entities of weird magic. Instead he opened a portal that the hungry Elder Gods eagerly attempted to breach, and it took the gods of your world to collapse Tsathzar Rho's fortress and seal the threat. Dherro and kobolds recently mined into this mountain, where the fortress once stood and accidentally re-opened a breach where the chaos of the Elder Gods was able to slowly seep into and warp both reality and the humanoids it touched. They also reshaped Tsathzar Rho into an abomination and made him into a servant that was to cross into your reality and lead the assault of chaos unto earth. You encountered him before he finished gestating.
As for the magic items, they were some minor pieces of some of his old equipment he was trying to get to in order to augment his strength. You find:
- Glass vial of silver dust worth 100 gp

- Glass vial of diamond dust worth 800 gp
