1. Llwch Ewin

      An English lake where the boar Twrch Trwyth made a stand against Arthur and his warriors during the grand hunt. Twrch Trwyth killed many men - including Echel Pierced Thigh and Garwyli - before he fled on to Llwch Tawy.

    2. Llwch Lleminawc
      Llawwynnawg, Lloch Llawwynnyawc, Llwch Windy Hand

      One of King Arthurís warriors in the Preiddeu Annwfn. He is perhaps taken from the Irish folk character Lug (he is mentioned as being from "across the sea").

      According to the legend, he fathered a number of sons who became Arthurís warriors, including, probably, Llenlleawg. Several of his sons were named Gweir. His first name means "lake", while his second seems to mean "striking hand". His relationship with Lluch Lleawg and Lleminawg is uncertain, but he may be identical to either of these characters. He may be the origin of Lancelot and Lot.

    3. Llwch Tawy

      An English lake to which the boar Twrch Trwyth fled while pursued by Arthurís warriors. At the lake, Twrch Trwyth and his piglets split up. From here, the boar went on to the Havren River.

Llwch is the ancient Welsh for an inlet of water, a lake. It corresponds to the Irish lough, Scotch loch, and the English lake.
