The Blood Pact

Details
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 the collectable parts of a new costume item.

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.

Trivia

 * On the day when the quest has been released, the spoiler said: "No information on the rewards for this quest will be available until the cult activity is identified and thwarted. Res, though, that there will be several useful items for new adventurers."Glitchstaff.png
 * With the release of The Blood Pact, there are now 300 Quest Points available in the game. If you have 300 points, make sure you speak to Xenia again after completing The Blood Pact, as she has a special reward to help you show off your dedication to quests. Unlike the Quest Cape, the new item's requirements will stay fixed at 300 Quest Points even after new quests are released – once you have 300 Quest Points, you can wear the item forever. Item is Helm of Trials, it has no bonuses.
 * There is a glitch, when casting a spell or meleeing with the new staff, the staff seems to float
 * There is another glitch, when you get your reward and she gives you the runes, the text says "Xenia gives you some air runes" and you actually get mind runes, vise versa for the air runes.
 * On the day when the quest has been released a lot of pures complained about the defence reward.
 * There is a glitch that allows you to spawn an infinite number of Dragith Nurn, by simply clicking on the statue-plinth.
