You must have 50gp, 5 blood runes, 10 mist runes, 10 lava runes, tinderbox, hammer, and other items; you will get them through the quest: axe, pickaxe, 1 log, 5 iron bars, small net, and a brown apron. Teleports to the following places: Ardougne, Yanille, and Falador are recommended. Any emergency combat teleport, strong melee and ranged gear are recommended. Quest length: 1 hour.
To start the quest, go to Herman Caranos at the Fishing Colony fence (go to www.runesource.co.uk to find more). Head to an area northeast of the Gnome Stronghold. Here two characters will be stand at a boat. Talk to Devin, then chat with Kathy. Kathy will take you across for a payment of 50gp. Talk to Herman Caranos and offer him a hand with his troll troubles. He wants you to go to the Wise Old Man by the Draynor bank. In case you are not convinced of the old man's questing prowess, watch the cut scene - I wonder how long I must follow Guthix before I can kill a Drunken Dwarf...
Once you arrive in Draynor Village, go see the Wise Old Man across from the bank. He will help you but he wants 5 blood runes, 10 mist runes, and 10 lava runes. If they are in your bank withdraw them and give the Wise Old Man the runes. You can craft them too.
Now kit out in your melee gear and head back to the Fishing Colony. Talk to the Wise Old Man once you've traveled over the river and enter the Fishing Colony. Here you will fight sea trolls (level 79) and once they're all dead you will utter something along these lines in chat. Go into the Fishing Colony and talk to Herman in a building at the Eastern Wall. He tells you to go and help out around town, as Franklin the Engineer and Arnold the non-fictional banker and shopkeeper need a hand.
Franklin needs help fixing the barrier fence with sheets of iron. Either pick up the axe and the pickaxe and get a log and the iron just outside of the colony of get them from your bank somewhere. Put the log in the Iron Press near the furnace and light it. Then walk to the other end of the machine and press 5 bars of iron into sheets of iron. Hammer the sheets into the broken fence on the west side of the colony. Talk to Franklin when you're done.
Now it's time to help Arnold out. Arnold is in the general store and bank building. He wants monk fish caught and he will hand you a small net to do it. The fishing spots are on the north side of the colony, where it meets the ocean. Catch 5 monk fish (trolls will pop up every so often to attack you, ranging from level 67-101, kill them) and go cook them on the range to the south. Hand the cooked fish to Arnold.
Go back and talk to Herman again. Herman and the Old Man have made a defense plan. They need an army for it, though, and fast, an army for the undead. Head for Wizard Frumscone in the basement of the Magic Guild in Yanille and talk to his master of zombies about it. After some chat he will let you down easy with the hint that you should go to the necromancer south of Falador, Malignius Mortifier.
Time to grab your pickaxe. Malignus will help you after some begging (Malignus obviously wants to feel powerful, the fungus summoning nitwit), but he want 7 bones. Go get them.
He will make you bone seeds now, but you need to transport them. Go to the Crafting Guild (40 crafting, brown apron), and talk to the master crafters about bone seed containers, one of them will help you out. You need a pot and a potlid. Go make them while you're at the crafting guild. DO NOT throw away that pickaxe yet. Mine 2 clay ore at the Crafting Guild and make the pot and lid.
Now replace your melee gear with your magic gear. Hand the pot to Malignus he will put the seeds in the pot for you. Then he will teleport you to the Fishing Colony. If you haven't rekitted for battle yet, do it now. Return to the Colony on your own accord. Then give the pot to Herman for the fight to start.
A nice combat cutscene will begin of the Old Man's "Swan Song", is shown, and enjoy the fight. The Sea Troll Queen (Level 170) will then appear and attack you. Prayer will help. Kill it and return to Herman for your rewards.
