What help would you be needing, exactly? Israelite's map is good, though. The main changes by 1326 would be:
- The conquest of the "Western Kipchak Horde" by the "Khanate of Nogai", and subsequent reunification of the Golden Horde (note, the capital de facto moves to Crimea) after some more instability;
- Major Muscovite expansion via inheritance and war; notably, this includes Peryaslavl-Zalesky (Pereyaslavl on the map), Kolomna (in northern Ryazanese territory) and Mozhaisk (eastern Smolenskite territory). The bid for power in Vladimir has temporarily backfired, though; instead, the Tverite prince named Dmitriy the Terrible-Eyed (excellent epithet, that) has taken over Vladimir, though this won't last for long.
