A is for ... Alderley Edge

The area of Alderley Edge in Cheshire, England, is steeped in anchient myths and folklore.

This part of England is said to be the home to King Arthur and his men, who are thought to be sleeping under the sandstone cliffs.
It also has strong links with the wizard Merlin.

The legend of Alderley Edge tells of a farmer who was on his way to market with the aim of selling his horse.
As the farmer passed the sandstone cliffs that make up Alderley Edge, he came across an old man with a long white beard who was wearing strange, dated clothes. The old man asked to buy the farmers horse, but he refused as he was sure he would be able to get a better price if he sold the horse at market
Once the farmer reached the market, however, not a single offer was made on his horse so, feeling rather sorry for himself, he set off back home.
The old man appeared to him again and asked if he could buy the farmers horse. This time the farmer agreed and the old man asked him to follow him through some trees. 
The pair came to the foot of the sandstone cliffs and the old man touched the rock with his staff.
There was a deafening rumble as the rock parted to reveal a huge, dark cavern.
The old man told the farmer not to be afraid and asked him to follow him inside.
Once the farmer's eye adjusted to the dark he was amazed to see that the cavern was full of hundreds of warriors all in a deep sleep, each with their own horse asleep next to them.
The farmer suddenly realised that the old man must, in fact, be a powerful wizard.
The wizard explained to him that all the sleeping warriors were ready to awake and fight for their country, should they ever be needed. He then led the farmer further into the cavern and showed him a large pile of jewels and gold, telling him to take as much as he wanted as payment for his horse.
The farmer picked up handfuls of gold and coins and filled up his pockets to bursting. He then walked back outside and, feeling overwhelmed, took off running for home. 
The cavern closed behind him with a thud and was never seen again.

In the area where this magical tale takes place there is a well. And near this well there is the face of a man carved into the rock, above an inscription which reads:

"Drink of this and take thy fill, For the water falls by the wizard's will"

The date and origin of this carving is unknown.

Could it be one of the sleeping warriors, keeping watch over the land?
Or maybe it's the mysterious wizard himself?
