As announced in our Blizzplanet Update few days ago, we added Diablo Lore and History. And Warrior, Rogue and Sorceror Class description. This material comes from the Diablo Classic Manual. Special thanks to StarcraftFreak from WC3Campaigns for his contribution.
Stay tuned, in a few days, we will add the in-game gossip and mission text from NPCs to introduce our new Diablo II and Lord of Destruction Lore section.
