Each city is split into different City Zones. Possible zones include Airspace, Outer walls, Tunnels and Garrison. Not all cities have all types of city zones, and some may have some that aren't listed. However, each city must have a Garrison Zone. Furthermore, each City Zone may be split into different sub-zones.
Airspace can only be entered by Flying units. Airspace can attack, or be attacked by, Tower garrison sub-zone.
Outer Walls is a city zone that borders the Courtyard garrison sub-zone. Outer Walls can only be entered once the walls have been breached. The more units on the wall the harder it is to breach. Erf-b1-p098a
Outer Walls can contain a Gate sub-zone. Gates, while weaker than other sections of the wall, allow non-flying, non-tunnel capable units to enter and exit a city.
Outer walls can also contain towers that boost its defensive value. It has yet to be seen if outer wall towers are a true sub-zone or an enhancement providing addition.
Main Article: Tunnels
Tunnels can only be entered by light Units or units with a natural ability allowing them to enter tunnels, like Spidews and Sourmanders. Tunnels can attack, or be attacked by, the dungeon garrison sub-zone.
(For a description of the Unit attribute Garrison, see Garrison Ability.)
All cities have a garrison zone. When the garrison falls, so does the city. Garrisons can contain sub-zones.
Each sub-zone could be attacked from only one of the main city zones. Outer Walls only connect to Courtyard, Airspace connects to Tower, and Tunnels connect to Dungeon. Once an attacker enters a Garrison zone, it can assault any other garrison sub-zone.Erf-b1-p116a
Courtyard can only be attacked from Outer Walls, and then only when the Garrison Walls have been breached.
A caster at the top of a tower gains a bonus to casting.Erf-b1-p116a A tower's bonus to casting and the efficacy of air defense spells laid upon it may be directly proportional to the height of the tower.IPTSF Text 20,IPTSF Text 30 Shockamancers are particularly good at charging towers' and laying air defenses. LIAB Prologue 26
Dungeon can only be attacked from Tunnels, which can only be entered by light Units or a unit with a natural ability allowing it to do so. The Portal Room is located on this level in all all capital cities.
A dungeon gives a bonus to tunnel units and Dirtamancers.Erf-b1-p116a
Each city may have different Garrison sub-zones, depending on it's construction. For instance, a subterranean city wouldn't have an airspace and therefore, no tower. Similarly, not each garrison sub zone needs to connect to main city zone. A subterranean city might have a courtyard, but no outer walls. Spacerock is one such oddity, having dungeons but no tunnels (this is marked up to being the unique aspect that comes with being a Level 5 city) Erf-b2-p25.
