@rush99999 Jenk succeeds the secret roll:
Jenk remembers reading something in the Nantambu Clarion, a local newspaper, about how these canals have been getting stopped up from time to time. The article was brief, but listed several techniques used by the governing authority to temporarily address the issue. The first was leverage of a wide wooden beam hoisted and suspended above the canal and used to clear the path. This method was expensive and slow, scraping all the way to the bottom of the canal. The second, and most often used, was to dam off the canal, drain it, and clear the blockages this way. The third was used in a pinch... The gases rising from the sewer aqueduct were flammable, and under the right supervision, a simple flint and stone could ignite the refuse at the top, burning off the top most layer and loosening the blockage as a whole.
