This artefact was recently found by scientests from Thunderdallas, showing part of the 1279 Battle of Isauricus. It shows the Roblexian King, Procas II, sieging down the gates to the Sextalian city, while the defenders prepare to narrow down arrows on the army. Maybe this is what happended at least 744 years ago, where modern tech wasn’t there, and Pixel Island was in the Medieval Age.
