Runes Shards;
- You get 1 AW Rune for clearing a province.
- You can also get them from participating in Tournaments, at certain rounds you can get many AW Runes.
- You place the Rune(s), into the circle of the Ancient Wonder (AW) that it's for. You need to place 9 Runes to complete the circle to build the AW or upgrade it (certain levels)
Broken Shards;
- Sometimes when you place a Rune into the circle, it Fails! Turning it into a Broken Shard
- You can get Broken Shards from participating in Tournaments, at certain rounds you can get many.
- You can also build a Ancient Wonder (in later chapters) that gives you 1 or more Broken Shards for free, depending on the AW level.
- You need 10 Broken Shards, to equal the value of 1 Rune. In the circle, failing many times will eventually give you enough Broken Shards to turn it into a Rune.
- 10 Broken Shards = Any 1 Rune. Meaning you can place that 1 Rune into any AW you want.
Example; you have a Golden Abyss and Tome of Secrets Ancient Wonders. You want to put Runes into both. You start and finish Golden Abyss, at and realize you now have 10 Broken Shards, you can now use those for Tome of Secrets, instead of having to use it on Golden Abyss. Even if all the Rune that failed and turned into a Broken Shard, came from Golden Abyss Runes.
Hope this helps.

Although my cocky side tells me, I explained quite well, lol
Good luck!
