This will require several simple and complex functions:

• Find a way to determine world age onEnable
• Take a world seed as output and output a Map object populated with all stronghold approximate locations.
• Take a Map of those locations and check surrounding chunks for end portal frames
• Store whether the have an eye in them or not, their facing direction, etc in file

• etc
