No problem. Back to the topic of Dragon Age plans, I don't expect Myrn to get the staff after one quest. It's more like she does the Alienage a few public services that tests her skills and than she gets her staff. Here's a list of things I had planned for Myrn to try.
Find a lost child - An elvish child has been gone for two days. The mother and father had an argument about how her father could get into trouble stealing supplies for them from a ship (He works as a package handler at the docks). This will test Myrn's ability to gather information, from talking to people, tracking/finding evidence, and will lastly end with Myrn having to convince the child to come back home. She could always force her, but than she won't get a reward (The parent's being poor elves have nothing to give, but the girl did find a
magic amulet while she ran away).
Deal with some human thugs - Some homeless humans have come to harass and sometimes hold up elves for what little belongings they have. While so far hasn't gotten any worse than a few shake downs, many of the elves fear what would happen if the thugs get more ballsy. Killing them would be the simplest option (Rewards some silver coins and their iron daggers) but if Myrn can somehow convince the thugs to stop bothering the elves peacefully they will reveal where they've been stashing their ill-gotten gold. It can be given to the elves for no reason but maybe good feels or kept because it's 10 sovereigns. The location will not be revealed if the thugs are killed however.
Retrieve stolen heirloom - Some thieves have burglarized an alchemist's home and stole his family's sword. The thieves can't be reasoned with and there will be a fight (There are five of them). Including some low-level loot (Five Grey Iron Daggers, an Iron Dwarven War Axe, two Elm Crossbows, an Iron Buckler, assorted rough leather armor), the heirloom is a magical Grey Iron Dar'Misaan that imbues the wielder with energy (Meaning that it gives you a Stamina/Magic regeneration). Myrn can either keep it or give back to the owner, who will give Myrn some assorted potions and salves.
Deal with the Blood Mage - A family of elves took in a runaway elfish mage from the Circle recently. When the next day came, the entire family was killed in a bloody ritual. The community are in fear of the blood mage (Who's an elf no less) and want someone to take care of it. They don't care if Templars come in, though one person in particular is another runaway mage who doesn't want the Templars to find him, and will hire Myrn to take out the Blood Mage. We will have to fight the Mage, some demons he summons, and anyone else he controls with his magic. He has a decent level staff (Grey Iron Magic Staff) and a the
Blood Ring. Giving the Blood Ring to the mage (As proof that the blood mage is dead) and he will gift Myrn with a Tome of Arcane Technique.
I'm afraid that since this is mainly Myrn's personal quest, there won't be equal reward for everyone else. Granted, you can take whatever Myrn's reward is from her if you so desire, though she may take offense depend on how you go about it. Regardless of what rewards she gets, so long as she completes three of them she can do one more quest to get the Vhenadahl Heart Staff.
A Mother's Memory - A while ago a strong elvish woman by the name of
Adaia was killed by a gang of humans. She fought back as well as she could, but ultimately was slain and her
dagger taken. Her late husband,
Cyrion, knowing that even the deaths of the human will not bring back his wife, still wishes for her dagger to be returned to it's rightful owners. And so Myrn and anyone who's willing to accompany her will have to go on a mildly long quest to find out more about the mother's killers and eventually track them back to their home (It's a noble's house). From there how we get back the dagger is really up to whoever is involved. We could sneak in, fight everyone, or using a cunning tongue. Or just buy it, but it's out of Myrn's budget (She wouldn't be allowed to buy it anyways). We can keep the dagger or return it to Cyrion. In doing so, word of Myrn's actions for the Alienage will reward her with the Vhenadahl Heart Staff.
Just to link it to the cannon, the suppose end of this quest is that Myrn returns the dagger to Cyrion. Additionally, all these quests require Myrn to be in the party. I imagine that sometime between or after getting Fang back to Cyrion, the Grey Wardens might have heard of the Dalish Elf in the Alienage, which hopefully will allow Myrn a chance to join them in earnest.
