Used in event/collision data checks routine at 57293 - for all room event checks - keys & chests, doors, servant picking up objects, missiles, energy draining/restoring objects

• These are dynamic tables that hold a changing number of 4-byte room event data sets
• The number of sets will grow and shrink as the routine at 54740 re-evaluates the data in these sets
• The first byte in the table (1 or 2) acts as a counter for how long the event should remain in existence (for collision checking), as the two connected objects may both be moving on-screen.

Byte	Value
1	1 = Event remains in existence for 1 more game cycle 2 = Event remains in existince for 2 more game cycles 255 = End of data sets
2	Event/collision number. Event actions include: 1 - missile 5 - Servant 17 - Door handle (open/close) 136 - Maroc entering portal door in room 81 137 - Caliburn being used on Avelach to complete the game 253 - Energy restoring object 254 - Energy draining object
