Welcome to I Solemnly Swearthe official tumblr
I Solemnly Swear is a Harry Potter roleplay set in the late 1970s. The timeline began in 1976, as James Potter, Sirius Black, Remus Lupin, Peter Pettigrew, Lily Evans and others were starting their final year at Hogwarts. Since then, it has progressed to early-1978; the Marauders have graduated, testing their wings in the real world while younger students find their place at the school.
It’s not all fun and games. Voldemort and his powers grow stronger, and his follower count seems to be steadily on the rise. He’s proven that he can cause mayhem anywhere, from Hogsmeade to St. Mungo’s to Diagon Alley. The Order of the Phoenix has no idea where he’ll strike next, or how bad it will be. Hogwarts is the safest place to be, especially now that there are Auror guards around the castle and patrolling Hogsmeade. The Ministry for Magic is not much help; over the Christmas holidays, the Minister - an outspoken Muggle and Muggle-born rights supporter - was assassinated, leaving the government scrambling to re-organise and sort itself out. Students who went home for the holidays have gone missing, with no trace of whereabouts or any sign that they are still alive.
Currently, ISS is operated by its friendly staff of six: three administrators and three moderators, easily identified by their purple names. Given that it was founded before the release of Deathly Hallows, ISS has an unusual canon timeline - something that sets our site apart and in which the members take considerable pride. Although many of our events closely follow the canon timeline (such as school years and ages of the Marauders), we’ve taken liberties with other characters to broaden our creative horizons. Although it may seem odd at first, we saw no reason to discard characters we’d come to know and love simply to follow a canonical timeline, and we can boast that our list is unlike any other sites’.
ISS is always open to new members! We are a literate roleplay with a requirement of 500 words per post; however, we do have the occasional group thread where shorter posts are permitted. Rules and site information are clearly posted and accessible to both members and guests, and our staff is almost always available to answer any questions you may have. Please read the rules thoroughly before posting an application (especially for a major canon character) to avoid any confusion.
To be taken to various areas on our site, please see the links in the sidebar. Please note: this will take you away from tumblr and to the proboards site where ISS is hosted and played.
