In 487, Theodoric's armies were quite strong, as he had just taken control of the troops of Theodoric Strabo. Theodoric, looking to extort the emperor and increase his own power, put Constantinople under siege. OTL he and Zeno worked out a deal where Theodoric would move west and conquer Italy. But what if Theodoric had set his ambitions towards the eastern capital? Let's say he secures an alliance with the Vandals and uses their navy to blockade Constantinople’s ports. Could he have taken the city? Could he have held the city for long? If this much is plausible, what happens next? If Theodoric reigns until dying of old age, he would rule for the rest of OTL Zeno’s reign up until Justin’s reign.
