4 byte sets indicating doors and the room number of their connecting door. Address pointer to these sets is stored at DAF5.

Byte	Value
1	Connecting room number 1
2	Connecting room number 2
3	Door properties byte (from EB4E) Bit 0 set = door is visible (default) Bit 2 set = door will need erasing (default) Bit 4 set = door is open Bit 7 set = the door Maroc has just gone through (stored at EAF5, copied here in routine at C5E0)
4	Event value to check for door collisions at CA75 when Maroc goes through this door: 0 = can be opened by Maroc bumping into it 1 = can be opened by Maroc bumping into it, the servant, or a deflected missile Other value = the key or spell (e.g. OPEN) number that opens this door For example: Connecting door set 28 - event value = 12 - corresponds to the key event that opens it - stored at second-to-last byte of the key item data set at 746B Connecting door sets 163 & 165 - event value = 10 - corresponds to the OPEN spell - stored at byte 6 of OPEN spell data set at 6E9C

Each of these data sets tell us which two rooms each door connects.

• The first two bytes of each data set here indicates the two rooms that this door connects
• In the room data table at 61A9, the penultimate bytes - preceding each end byte of 255 - reference the data sets here, for each of the doors in the room
• For example, in the above image, a door connects room 2 to room 5. This connecting door is at 679C
• Similarly, the door connecting room 5 and room 6 is at 67A8
