In this sentence:

> 当時の人間どもの手 **である** 改造を施された

I'm not sure if である is being used as the copula or the で part is used to mean
"by the hands of this people" as in means of action

question
translation meaning usage
Usage of である in this sentence
```

    で  : by
    ある: one(or some)
    
```

ある is just modifying 改造, like "ある日(one day)". If splitting the sentence by a
space, it becomes:

```

    当時の　人間どもの　手で　ある改造を　施された
    
```

or changing its order:

```

    ある改造を当時の人間どもの手で施された
    
```
