Arc Name: The Exiled
Arc ID: 65928
Morality: Heroic
Faction: Custom
Creator Global/Forum Name: @Hymnoxlyn
Difficulty Level: Easy to Moderate (1 AV at the last mission)
Level Range: 1-50(Level 50 suggested)
Synopsis: Portal technology is innovative, amazing and useful. However, a new threat reminds us that portal technology can also be extremely dangerous in the wrong hands. (This arc was designed to be solo friendly and level friendly, but is intended to be played at level 50 with a small group.)
Estimated time to play: 30 minutes to 1 hour
Give it a whirl! Any and all feedback welcome! The arc should bring the fun back to the fight with a familiar elemental group powered up, but not to a frustratingly hard difficulty.
Arc is posted below. I've already been warned by Sins it's a little too Me-centric (meaning it has the most significance to people who have seen/know me in game as Rejolt). Sighs... perhaps I can do a re-work in the future for why someone outside the inner circle would care.
That said:
Arc Name: Rewriting Origins
Arc ID: 1059
Morality: Heroic
Factions: Contaminated, Clockwork, Nemesis, Storm Sentinels, Custom mobs (only in final 2 missions).
Creator Global/Forum Name: @Rejolt
Difficulty Level: Easy for first 2 missions, average for 3rd (Nemesis fight with a strong ally), very hard for 4th (15-minute kill all on a burning forest map - meant to be impossible for story purposes... but people keep telling me they do it and love the challenge) and finally the 5th mission is hard with ambushes, defendable objects and 2 EBs with no allies.
Level Range: Any, but at least DOs for 3rd mission, thereafter you'll need an SO'd toon at least with the ability to solo and survive or a team that can kill quickly.
Synopsis: The hero Rejolt has done years of good deeds for Paragon City, but most of it solo. She's tried too hard to increase her power and it will eventually lead to her downfall. You'll get to witness her beginnings, her biggest triumph and eventually her downfall before fixing her in the present by digging into her mind.
Estimated time to play: 35 to 40 minutes for your favorite buzzsaw, can go as long as a hour otherwise.
Thank you, City of Heroes, for giving me a superhero social network combined with amazingly smooth game play. Petitions signed with realistic expectations.

Arc ID: 76190

Synopsis: Part 1 of a 3 part series dealing with the Archvillain King Midas's attempt to use the players to take control of the Cap Au Diable underworld. Join forces with the King of the Goldbrickers as he seeks your aid in crushing rival gangs. The work is dirty, and the money is good. This first story centers around a custom splinter group of Hellions with a powerful new leader. It culminates in a mandatory Elite Boss battle with the Hellion leader and many of his followers. The rest of the story will follow in coming weeks.
If anyone will try my story and leave me legitimate and honest feedback, I promise to do you the same service for one of your stories. I hope you enjoy!
