In Aid of the Myreque

In the hideout behind the Canifis pub, go through the secret wall and squeeze past the stalagmite on the east side of the cave

Talk to Veliaf Hurtz.

Travel to Mort'ton. The fastest way is by heading south of the cave, exiting through the doors, climbing the same tree from In Search of the Myreque and using the swamp boat south, or using a portal to the Barrows in War's Retreat.

If you need a piece of food, there are snails to the west of Mort'ton that can be cooked with level 12 Cooking.

Speak to Florin, south of the bridge to Burgh de Rott, who won't let you pass yet. (Make sure to finish dialogue options)

Search the chest.

Use food on the chest.

Jump the gate.

Talk to Florin.

Climb over the broken down wall in the building just south-east of the well. It'll be near an unreachable pile of rubble that you can mine.

Mine the rubble to clear the trap door, then open the trapdoor and climb down.

Mine and use spade to remove all the rubble piles (15). Your bucket can be emptied on the pile outside the pub.

1 bucket will allow you to mine 3 piles before it needs to be emptied in the pile outside. There is a bucket next to the well if you need one.

Bucket(s) of rubble may be disassembled or alchemized to avoid the need to empty them outside.

Any items left on the ground when you climb back up the ladder will be lost.

Go up and talk to any villager.

Climb the ladder outside and use a plank on the Broken Roof (3 planks, 12 nails required).

Climb down and use a plank on the damaged wall (3 planks, 12 nails required).
