Sprung a Leak

A fissure has opened in the great dwarf-canal leading down from Thorin's Hall, threatening to flood the Vale of Thráin.

Description
Stage 1

'I am Tindr, Master Builder of Thorin's Hall. The great canal, for which I am responsible, has recently fissured. The crack has not yet become a serious threat, but it is only a matter of time, and I haven't any builders available to assist with its repairs. Could you help me seal the fissure?

'I need to mix a mortar to seal the crack but our stores are barren. I will need stone and gypsum from the new Mirkstone Tunnels and sand from the Rockbelly Pit. The Mirkstone Tunnels are above the great statue of Thorin to the north-west. Fool goblins dug another entrance after we closed off the original with the Arming Cave. The Rockbelly Pit is to the south-east in the Winterheight.

'If we do not seal the crack soon, it may break, flooding the Vale of Thráin below.'

Tindr is in the courtyard in front of Thorin's Hall. Sand is in the Rockbelly Pit south-east of Frerin's Court in a place called Winterheight. Gypsum and small stones can be found in the Mirkstone Tunnels above Frerin's Court to the north-west.

Tindr, the Master Builder of Thorin's Hall, has asked you to collect various ingredients for a mortar with which to repair a leak in the canal wall.
