The search for the Holy Grail led Sir Galahad, Sir Percival and Sir Bors all through the kingdom, and eventually to the castle of King Pelles.

Then rode they a great while till that they came to the castle of Carbonek. And when they were entered within the castle King Pelles knew them. Then there was great joy, for they wist well by their coming that they had fulfilled the quest of the Holy Grail.
- Malory.

In order to celebrate, King Pelles ordered a great feast, and each of the knights took his place at the table. During the feast the hall doors swung open and in came maidens carrying a silver dish, candlestick, and a bloody spear. The last maiden carried the Holy Grail. As if in a trance Sir Galahad got up and joined the head of the procession, which went throughout the castle until it reached the chapel. The holy vessel was then handed to Sir Galahad who drank the Holy wine and all its power was bestowed upon him.
