"Some adventurers never retire, but, as they get older, they learn the value of teamwork. Veteran adventurer Xenia has seen some Zamorakian cultists take a prisoner into the catacombs beneath Lumbridge Church, but she wants another adventurer to join her before she heads in after them. Xenia was there when the catacombs were built, so she knows something about the dark secrets that they contain. If the cultists have discovered those same secrets, then their prisoner will be only the first of many victims. It's up to you to stop them. The Blood Pact is the first free-to-play quest Jagex has released in many years, not counting the tutorial and seasonal events. It is aimed at new characters. Completing the quest will reward players with a set of weapons and access to the Lumbridge Catacombs – a dungeon that’s also designed for low-level characters, full of new monsters to fight, which drop parts of a mask (there are 5 in total)! There are also 6 different statues of demons in the dungeon which xenia will pay you for, equaling a total of 2500 coins." The Blood Pact was a Free to Play quest released 15 March 2010, hitting the 300 quest point total. New Free to Play items were released with the quest along with a reward for people who managed to obtain 300 quest points. It involves Xenia getting rid of a Zamorak cult in the Lumbridge catacombs.

Also, if you obtain 300 quest points, you get a new helmet named Helmet of trials.
