Cross
Crois
A cross to which Meliant of Dianarca and Galahad came after they left the abbey where Meliant had been dubbed knight.
It is a rendevous point of the knights who start in the last quest of Lancelot.
It’s located at the foot of Tertre as Caitis. It might be the same “crois” as the “crossroads of five lanes” at the entrance of a forest. Perhaps identical with the monument Black Cross.
