Gower Quest

Gower Quest is a quest that was announced at RuneFest 2015. It was released as part of RuneScape's 15 Year Anniversary Celebrations. The quest was released on 20 June 2016 and is a standalone quest with minimal requirements. The Gower Quest had input from Andrew and Paul Gower as guest designers and executive producers, as well as featuring them as in-game characters. The quest's plot sees the brothers living as cabbagemancers on the Gower farm, south of Varrock, failing to grow cabbages in their cabbage patches. The player has to create an amulet of cabbage-speak to find out what the cabbages want.

Cabbage Disaster
Start by talking to Andrew, Ian, and Paul just southeast of the Varrock lodestone. They are excited to have a real-life adventurer, and ask for your help to figure out why cabbages aren't growing.

Cabbagespeak Amulet
After talking to them, proceed to the room directly west of them. Search the crate in the northeast corner to get a piece of pure essence, which has a flip option on it. Clicking flip turns in into a life rune. Proceed to the cabbage patch to the southwest of the house and search the scarecrow to get a cruciferous mounting. Then go northeast into the courtyard and search the water barrel to get a brussels sprout. Combine the Brussels sprout and Cruciferous mounting to make a Brassican amulet (unstrung). Then head to the rats east of the house and search the food trough to get a broccoli root. Spin this at the spinning wheel in the house to make a broccoli string. Combine with unstrung amulet to make Brassican amulet. Finally, use the life rune on it to turn it into a cabbagespeak amulet.

Rioting Cabbages
Go back to the cabbage patch and speak to Crispy the Cabbage. He explains they are rioting, and that they want partyhats. Return to the Gower brothers, who will wonder why cabbages want partyhats, but give you a stack of 4 pink partyhats. You cannot put them on, sadly. Return to the cabbages and give them the partyhats. Afterwards, Crispy the Cabbage will explain the cabbages are magical beings, and if there is a problem then there is a problem "behind the sceneries", and will get into your backpack. Return to the Gower Brothers to get a disk of returning, which needs to be used in the Dwarven Mine north of Falador.

Black Hole Experience
Once in the Dwarven Mine, use the disk of returning to scan, and follow the direction. In the northwest corner of the mine, you will use the scan and get taken the realm of Behind the Scenes. The screen is completely black, and you need to search around for things in the dark. Start by searching the table and get a pet rock. Use the pet rock on the wall to hear a grinding sound. Search under the table to get an orange, and eat it to get a small key. Use that on the bumpy wall to get a tinderbox. Use the tinderbox on the Scary wispy thing to retrieve a skull. Use the skull on the unusual shape to get a portal to appear. Go through.

Behind the Scenes Pub
Once in the pub, talk to Spiral Orb, the DJ. She will explain the life altar is broken, and you need to retrieve pieces. When asked, she states that you should talk to Lucien, Steve (the chaos elemental), and Thok.

Go talk to Lucien, he is at the northwest corner. He will then tell you that the first piece has been stolen from him. He will tell you it was the Wise Old Mans doings. The piece is in the vault of the bank but you have to figure out the four problems first. Go into the portal and speak to Clarie Hick. That will be the first problem. Go to the back of the bank and talk to Ernie the guard. There is the second. Check out the vault door and you will have the last two. You will then have to recruit four people. Talk to Romeo and ask him if he will help you break into the bank. He will tell you that you need to get him love advice from five people. Those five people will be the God Wars bosses. Go east and talk to each of them and they will tell you advice and go back to Romeo and tell it to him. He will meet you in the bank. Next, talk to Guthix, ask him the same thing and he will ask you to talk to cabbages for an actors position. Go just north and talk to one of the cabbages at the table. They will then tell you that they are interested in having Guthix as the main actor. Go tell him this and he will then teleport in the bank saying he will wait there. Talk to the penguin south of Araxxor. He will help you get into the safe, with no extra help. Next, you must find Tim and Crunchy, but you have to have five free spaces in your inventory first. They will tell you to help out the five Environment Artists by giving them a cup of tea which can be claimed by any bartender. Go around the bar and give each Artist a cup and then the two will meet you in the bank after you finish and talk to them.
