I have some ideas about your project. Maybe you can realize it.
Create world map of Titan Quest like Google maps but for game. How it relized in social club for GTA 5
Create Titan Calc with support TQ: Ragnarok and integrate with your database, where we can check stats with stuff and masteries. I know about http://www.titancalc.com/ but there is a bad interface, not support Ragnarok and not bugfixes from patches.
