After Keraunos' younger half-brother, also called Ptolemy, was named heir apparent and, in 282 BC, ascended to the throne as Ptolemy II, he had to leave Egypt, being a potential rival for the throne. He arrived at the court of Lysimachus, the king of Thrace and Macedon, and part of Asia Minor, where his half-sister Arsinoe was queen.

Eurydice
