The Empty Throne Room

The Empty Throne Room (also known as the Senntisten digsite) is the excavated remains of the throne room of Zaros in the ancient city of Senntisten. It is located to the east of the Digsite.

The throne room was excavated by Celia Diggory. According to her, it is full of latent divine energies. These energies had formed into crystals that covered the throne room when Celia first uncovered it, but they have been partially cleared away before the player arrives by Digsite workers and Doric and Son.

The player can assist in several activities around the excavation, training the Mining, Agility and Divination skills. The content is designed in a style similar to The Nexus, wherein it gives a total of 800,000 experience in each skill, in order to bridge the gap between levels 65 and 75 in these skills. Level 65 in at least one of the three skills is required to participate in the excavation. The player can also obtain Senntisten scrolls, which can be handed in to Celia in exchange for translated letters.

Helping the Excavation
There are three tasks that the players is able to assist with - mining the crystal formations, moving the cart by riding a Manual Auto-cycle, or transmuting the Senntisten crystal into different colours.

Of each of the activities, one of their nodes is empowered at a time. The empowered node will change around every minute, and using an empowered node will grant ten times the experience, except for depositing crystals.

Excavating the throne room requires a certain amount of co-operation. Crystals which are mined from the formations must be deposited into the Refinatrix in order to be processed. They are then carted up to the storage bin for transmutation. NPC Dwarves and Digsite workers will slowly move the process along without any player input, allowing players to do the activity they desire unless it is very busy. However, players will only be able to extract however many crystals are available in the Crystal storage bin for transmutation.

Mining
There are four crystal formations at the bottom level of the throne room which can be mined. Mining one produces Impure Senntisten crystals. Once the player's inventory is full, they should deposit them into the Refinatrix for others to process. Both the act of mining individual crystals and depositing them into the Refinatrix gives the player mining experience - 4.6 for mining it (46.8 when empowered), and 20 for depositing it. As well as this, one of the crystals is always empowered, to give ten times experience.

Agility
Agility is trained at one of the six Manual Auto-cycles in the centre of the throne room. Cycling on an Auto-cycle will give Agility experience drops every 1.8 seconds (3.8 experience at a time), which are ten times higher (38.2 experience) if using an empowered Auto-cycle. Two of the Auto-cycles are operated by workers, but these can be ridden as well.

Divination
At the top of the throne room, where one enters, there is a crystal storage bin where players can extract Senntisten crystals. There are four types of coloured crystal which they can be transmuted into - yellow, green, blue, and red. Each of these colours has a corresponding box that they must be deposited into. The experience gained does not vary for any of them (1.9 experience per crystal), except by which of the deposit boxes is empowered (19.8 experience per crystal). Transmuting crystals of the corresponding colour will grant ten times experiences, but experience gained from depositing crystals does not vary with the empowered box (depositing always gives 19.8 experience per crystal).

Senntisten scrolls
Training at any of the skill nodes has a chance to add a Senntisten scroll to the player's inventory. These scrolls can then be handed to Celia Diggory, at the top of the throne room, who will take and translate them. After this the player can ask for a copy of the translated text from Celia. She will also return destroyed texts to the player. The texts are gained in a specific order:
 * 1) Letter signed 'Pontifex Madromurt'
 * 2) Letter signed 'Pontifex Nabor'
 * 3) Letter signed 'Pontifex Bilrach'
 * 4) Damaged digsite letter

Trivia

 * On release, players were unable to use the Manual Auto-cycle if the Crystal storage bin was full, and the dwarven miners deposited crystals to refine much slower than they currently do. Both of these changes were made in a hotfix on the day of release, in response to player feedback.
 * The Infernal phrase Condita est in astra can be found above the mural on the easternmost part of the area. It can be translated to It is founded toward the stars. Interestingly, the 'it' refers to something feminine.
