Just what it says on the label. Two questions here:
1. Is it possible without crossing into ASB territory to keep the Empire in one piece after Alexander dies, or is the breakup inevitable? If so how might this be accomplished?
2. Assuming it can be held together, what does its future hold: expansion (perhaps the realization of Alexander's planned Arabian campaign, or another crack at India, or maybe even some forays into Europe), static, or decay/collapse under its own massive weight?
