I don't think of that as a 'shard' in the sense of a live server where players can meet in the same space. If, on the other hand, 'shard' simply means any server, then DI is like a repository from which I can download Ages, is this right?
Yes, a shard is a live server where players can meet in the same space. Deep Island ia a shard.
But a shard is made of several components, one of which is the data server, which as you said is like a repository from which you can download Ages.
When you are playing on the DI shard, your Uru client automatically downloads needed Ages from the data server. You don't use Drizzle. Extra Ages, such as fan-made Ages or those converted from other games, are made playable in the game because of special programs added to your KI (let's call this the on-line KI).
When you are playing off-line (using single-player Uru:CC or POTS), this automatic download cannot happen because there is no shard. You must manually download extra Ages from a data server using Drizzle. You can also convert Ages from other games to Uru format with Drizzle. Those Ages are made playable in the game using an off-line version of the on-line KI (called the off-line KI). You also install the off-line KI using Drizzle.
At some point, the on-line KI and off-line KI have been merged together so there is only one program to maintain, so it can be said that DI uses the off-line KI, that's what's confusing you.
