Dragon Age: Inquisition - Skyhold Information

Game Informer has new info on Skyhold, the castle which will be our base and home
in DA: Inquisition.  They've talked to Mike Laidlaw and Cameron Lee about

how the unique functions the castle serves, and how Skyhold gives players a greater sense of the Inquisition's power and progress.

Apparantly our home isn't exactly up to code when we first set eyes on it:

"When you first reach Skyhold, it's not in good shape," Laidlaw says. "There are holes in the roofs, it's wrecked, you can't even go to the entire castle because they haven't cleared out the rubble yet."

However, you can choose the way the castle interior will look like:

This isn’t The Sims, where you fuss over every detail of your dream home. The layout of Skyhold is generally standard, but the Inquisitor makes decision regarding the décor and other elements of the renovation process. For example, if a tower needs to be rebuilt, you can decide if it is outfitted to accommodate mages or Templars, depending on your allegiance. Or, if your character is a Dalish elf, you can furnish the castle with Dalish woodcarving.

Here's a rather interesing quote about the resources you'll need to keep an eye on:

When it comes to expanding your Inquisition, you need to track three different resources. The first is influence, which is effectively like your Inquisition's XP, and it grows as you adventure and complete tasks. When the Inquisition reaches a new level, you can spend points on global upgrades like the ability to carry more potions or the chance to harvest extra crafting materials. The second resource is power. While influence constantly grows, power is more of a currency that you earn and spend down. Power is used to advance the main story, but also to unlock optional areas at the war table. The third resource is time. The Inquisitor doesn't handle every problem personally, so special missions called operations (also unlocked with power) allow you to send agents to finish them in real time. After a set amount of time passes (some operations can take a full day or more), the mission is complete and you get your reward.
