Guelderine is a major city in the south of Eccles, at the base of the Duirt River - though it is called the Guelderine River in that region. Guelderine is situated at the foot of a large area of high hills. Amongst the noble houses in that region are House Helfi and House Celya.

It takes about two weeks on average to travel to Guelderine following the river - a shorter route is available through the hills, but that route is much more difficult and dangerous to travel.
