Due to the nature of the Steps Sewers, passages are occasionally blocked by debris. The passages will remain blocked for some time until reopening. Note that due to blockages it's often completely impossible to go from one area to another.
Some rooms are assumed to exist. These are uncoloured, but are expected to exist either due to the surrounding rooms or due to their presence on the map I used as a starting point.
Thanks to Blackening for sending me a map of the Steps Sewers for me to use as a beginning.
